1206-K Bearing Product Overview & Core Advantages
The 1206-K metric double row angular contact ball bearing represents a precision-engineered solution designed for applications requiring high rigidity and reliable performance under combined radial and axial loads. Featuring a tapered bore (1:12 ratio) and manufactured from high-grade chrome steel, this bearing offers exceptional dimensional stability and durability. Its double row design provides superior load-carrying capacity in a compact bearing size (30mm bore x 62mm OD x 16mm width), making it ideal for space-constrained, high-precision installations. Pre-lubricated and featuring a nylon cage for smooth operation, it delivers consistent performance across a wide temperature range from -30°C to 110°C.
1206-K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1206 | Standard bearing designation indicating metric dimensions (30mm bore, 62mm OD) |
| K | Indicates tapered bore with 1:12 taper ratio for precise mounting on adapter sleeves |
1206-K Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact construction provides significantly increased radial and axial stiffness compared to single row designs, enabling stable operation under combined loads (radial dynamic load rating: 3510 lbf).
Precision Tapered Bore: The K-suffix tapered bore (1:12) ensures secure mounting on adapter sleeves, eliminating internal clearance and providing precise shaft positioning for high-speed applications.
Optimized High-Speed Performance: The nylon cage reduces friction and enables smooth operation at limiting speeds up to 15,000 rpm, while the CN radial internal clearance provides optimal performance across various operating conditions.
Material Excellence: Manufactured from chrome steel for both rings and balls, the bearing delivers exceptional wear resistance and fatigue life, complemented by factory-applied lubrication for immediate operation.
1206-K Bearing Typical Application Areas
- Electric Motors & Generators: Particularly where tapered shaft mounting is required for precise positioning
- Industrial Gearboxes: Supporting shafts subject to combined radial and axial forces
- Material Handling Equipment: Conveyor systems and pulley assemblies requiring high rigidity
- Agricultural Machinery: Implement drives and PTO shafts where robust performance is essential
- General Industrial Machinery: Applications demanding reliable double row ball bearings with tapered bore convenience
